Error: Linker command failed with exit code1 #7

Closed suxiaoxinxin closed 7 years ago

suxiaoxinxin commented 7 years ago

When build the project always has a issue: Linker command failed with exit code 1. I really do not know how to figure out it. Thanks a lot!!!

@suxiaoxinxin Hi, can you please post the whole build log?

Do you mean this?

RobertBiehl commented 7 years ago

Can you check if you did the "Additional steps:" in README.md Unfortunately I did not yet get the pod configured correctly to not need additional configuration

I remove '-framework' from other linker flags, the error is gone but turn up some warnings:

Output of iphone6 like this:

Did I make something wrong?

Hi, it looks like you need to replace let caffe = with self.caffe =. You assign to a local variable, and not the instance property.

Wow! It worked! Thank you! You're so cool!

@suxiaoxinxin Hi, how is the performance on your iphone6? My iphone6 costs 30ms to do a single predict step which is far from @RobertBiehl 's 6ms.

RobertBiehl commented 7 years ago

@raininglixinyu Make sure you benchmark the correct part. Currently the pod ensures BGR color layout. This could cost some performance. I better remove the benchmark metrics from the README ;)

I think this pod should be easy to use first, then worry about performance. We're still a bit off the first goal.
